DESCRIPTION:
This series is a 6-digit multifunction programmable preset
Timer/Counter/Tachometer with a communication interface.
This series can be connected to a PC for programming and
logging of data. It has RS-232, RS-485, RS-422 Serial
Communications and supports Modbus protocol.

The Timer has 10 output modes and 10 timing ranges in 3
configurations.
The Counter has 12 output and 5 input modes in 6
configurations and scaling for displaying of specific units or
lengths.
The Tachometer displays rate per second (Hz) in 4 output
modes.
